I'm about to bite the bullet and replace my again 2012 15" MacBook Pro with a 27" iMac - the current 18 months interest free deals make it quite appealing and "she who must be obeyed" (ie. my better half) has said that I can look at a new machine if I want one - yay!
I'm in a bit of a quandary on which model to buy as I don't really do a huge amount on my current machine but am starting to get back in to a bit of coding and learning Swift plus I want to look at doing some minor photo and video editing (nothing large scale only family films of our daughter etc)
My thought as this stage is to go with the base model 3.4GHz 27" 5K iMac and upgrade it to a 512GB SSD. I'll get it with the base 8GB of RAM and can look at upgrading that myself later if I find that i need more memory (one of the main draw cards of the 27" machine).
On my current MacBook I'm using around 275 GB of space and this will increase over time as my Photos and iTunes libraries increase in size but I'm confident that I'll never need over 512 GB of storage in the machine, I have a couple of Linux boxes acting as Time Machine and general data/backup storage anyway but like to keep photos and iTunes locally stored for maximum access speed.
I'd welcome any thoughts on the pros and cons of only going for the base model but I really can't see the point in going to the next model up as all that is gives me for an extra $350 (NZ) is a slightly faster CPU (0.1 - 0.3 GHz) and a step up in video card, I cannot see any other benefit (you can upgrade it to 64GB or memory rather than the 32GB this machine is limited to but I can't see that being a real problem) and as I have never needed more than the CPU in my current machine (2.3 GHz i7) I can't see me needing anything more than the base model i5 will give (I have no need for more than 4 cores as I don't really do a lot that is CPU intensive and I have a VMWare ESXi server for VMs so probably won't require anything like that on the new machine)
Any and all thoughts/experiences appreciated - I'm going for the 27" as I've always wanted one and love the screens on previous ones that I have worked on for clients.
